Key points

  • Catering typically accounts for 55%–70% of the total budget. Set this first to allocate space for other items.
  • A 10% service charge is almost inevitable, so include it in the catering budget from the start.
  • Prize budgets should be 10%–15% of the total, with the principle of "fewer big prizes, more small and medium prizes."
  • Reserve 5%–8% for contingency expenses. Overtime fees, last-minute table additions, and taxi fares will certainly occur.

"How much will this event cost?" is usually the first question from the boss and often the hardest to answer.

This article uses real event management experience to break down reasonable proportions and price ranges in the Taiwanese market, enabling you to provide a solid estimate before even requesting quotes.

Proportions of the Six Major Categories

Using a corporate year-end party/spring banquet as an example, for an event with 150 people, the budget is roughly distributed as follows:

Category Proportion Description
Catering (including service charge) 55%–70% Banquet or buffet; this determines the overall budget scale
Venue 0%–10% Most banquet halls charge per table, no separate venue fee; independent venues are charged separately
Decoration and Materials 5%–10% Backdrops, table flowers, balloons, signs, table cards
AV and Equipment 5%–12% Projectors, lighting, sound system upgrades, live streaming, photography
On-site Interaction 3%–8% Photo services, interactive games, hosts
Prizes 10%–15% Raffle prizes and recognition gifts
Contingency 5%–8% Overtime, additional tables, transport, miscellaneous expenses

The structure of weddings is different: catering accounts for a higher proportion (65%–75%), prizes are almost non-existent, but decoration and image recording take a larger share.

Catering: Back-Calculate from Table Price

The table price (for 10 people) in Taiwanese banquet halls generally falls into several ranges:

Price Range Per Table Common Venue Types
Entry-Level NT$10,000–15,000 Community banquet halls, restaurant buyouts
Mainstream NT$15,000–22,000 Chain wedding banquet halls, mid-range hotels
Mid-High NT$22,000–32,000 Four-star hotel banquet halls
High-End NT$32,000 and above Five-star hotels, iconic venues

Calculation: Table price × Number of tables × 1.1 (service charge) = Total catering cost.

For 150 people, approximately 15 tables, calculated at a mainstream rate of NT$18,000:

18,000 × 15 × 1.1 = 297,000

If catering accounts for 60%, the total budget is approximately NT$495,000. This is the figure you can report to your boss.

Conversely, if the boss gives you a cap of NT$400,000, then NT$240,000 is available for catering, which translates to about NT$14,500 per table—you should look for venues in the entry to mainstream range.

Venue Fees: Clarify to Avoid Surprises

Most banquet halls "charge per table, no separate venue fee," but additional costs may arise in the following situations:

  • Not meeting minimum table numbers: Pay the difference or be downgraded to a smaller hall.
  • Non-typical time slots: Weekday lunches usually have discounts, Saturday evenings are the most expensive.
  • Independent/outdoor venues: Venue hire, cleaning fees, and deposits are extra, catering must be outsourced.
  • Overtime: Typically NT$5,000–20,000 per hour, depending on venue size.

Decoration: Ask What the Venue Provides

Many people spend repeatedly on items the venue already includes. When visiting, directly ask:

  • Is the stage, backdrop, and lighting included? What are the dimensions?
  • What are the default styles for table flowers, tablecloths, and chair covers? Can they be changed? How much extra?
  • Are there stands and signboards for the welcome area?

Decide on additions after confirming. For a 150-person event, additional decoration typically ranges from NT$25,000–50,000.

AV and Equipment

Item Price Range Remarks
Photography (still) NT$8,000–20,000 Depends on hours and whether editing is included
Videography/Highlight Editing NT$15,000–40,000 Same-day editing costs extra
Sound System Upgrades NT$10,000–30,000 When venue sound is insufficient
Lighting Upgrades NT$15,000–50,000 Often needed for performances
Live Streaming NT$20,000–60,000 Multi-camera, requires bandwidth

Reminder: Venue-provided projectors and sound systems are usually "adequate but not ideal." If you have performances or need to play edited videos, test on-site before deciding on upgrades.

On-site Interaction

This category has a wide price range due to numerous options:

  • Hosts: NT$8,000–30,000, depending on fame and hours.
  • Photo Services (photo booths, instant prints, photo walls): NT$15,000–45,000.
  • Large Screen Interactive Games: Free to NT$30,000. Basic quizzes, raffle wheels, and bingo have free options; custom branding, over 200 connections, or on-site support require payment.

For a 150-person event, an interaction budget of NT$20,000–40,000 usually creates memorable content.

Prizes: Fewer Big Prizes, More Small Ones

Prize budgets should be 10%–15% of the total. For a NT$500,000 budget, prizes are about NT$50,000–75,000.

Allocation principle:

Level Prize Budget Proportion Number (150 people) Unit Price Reference
Big Prize 40% 1–3 NT$10,000–30,000
Medium Prize 30% 5–8 NT$2,000–5,000
Small Prize 20% 15–25 NT$500–1,500
Everyone's Prize 10% Everyone NT$100–300

Winning rate is key to perception. Drawing 25–35 winners (about 20%) out of 150 people feels "easy to win"; only drawing 8, even if the prizes are expensive, most will feel it's irrelevant to them.

Don't Forget Contingency Expenses

The following items occur at every event but are rarely budgeted:

  • Overtime fees (more than half of year-end parties run over)
  • Last-minute table additions/reductions
  • Staff meal and taxi expenses
  • On-site emergency purchases (batteries, extension cords, tape, spare microphones)
  • Prize shipping for absent winners

Allocate 5%–8% of the total budget; it's good if you don't use it all.
